2 V LOOSE-LEAF FILE.

Application filed September. 25, 1919. Serial No. 326,119.

To all whom it may concern:

Be it known that I, CHARLES F. MoBnE, a citizen of the United States, residing at Athens, in the county of Athensand State 5 of Ohio, have invented certain new and useful Improvements in Loose-Leaf Files, of which the following-isthe specification.

The object of my invention is to produce a loose leaf file which will have. all the permanency of'a bound volume and yetcan be easily and quickly opened and locked, for convenience in removing or adding sheets thereto.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation view of my file;

line 2-2, in Fig. 1.

' F ig.3 shows-aplan view of my file, th parts being open and unlocked, the sheets having been removed-and a part ofeach cover broken away;

Fig. 4 shows a-.detail. view of a modified form of the carrying members; and

Fig. 5 shows a sheet perforated, as would be required, to be carried by the modified carriers.

Referring to the accompanying drawings, the reference numerals 10 and 11 indicate the upper and lower covers of my file, each of which is provided with a hinged portion 12 and 13 respectively, which portions are joined by the back 14. At the point of junction of the back with the lower cover, I have provided a hinge joint 15 which is designed to permit the back to fall down and lie fiat, and in line with the lower cover, when the file is open.

The numerals 16 and 17 indicate plates which serve the dual purpose of retaining the upper cover and back at right angles to each other, and to extend forwardly from the back to overlap the hinged portion of the lower cover, a recess, or slot, 18 and 19 respectively, opening forwardly, being provided in each plate. near its forward end and near its base. These said plates are mounted one near each edge surface of the file. and the filed sheets lie between them.

On the upper surface of the hinged portion of the lower cover I have mounted a I wire, and as the plates .eled immediately below the said slots the Fig. 2 shows a sectional view taken on the;

plate 20' with upturned lugs 21 and 22, se v cured one oneach end thereof, said: lugs to lie inside their respective plates I 16 and 17, when the file is locked, and also designed Specification'ofLetters Patent. Patentgd'App. 19,1921

on the saidv plate. 201' have secured two,

or more, upwardly projecting hollow posts 23 and 24. Each ofthe lugs2l and 22 has an elongated orifice and a spring wire, or

rod, 25, of a length practically equal to the Wldtll' of the file is guided as to its ends in said orifices, and passed back of the posts 23 and 24 (which by construction are 111 the rear of a line drawnbetween the V orifices in the lugs) thus holding said rod 7 in position with a rearward tension on the ends thereof. The slots 18 and 19 are deslgned to receive the ends. of the rod, or

16 and 17 are bevaction of pulling the back 14 forwardly and pressing downwardly on it, has the, effect of an engagement and the-springin the-rod forces 1t backto .a seat in the slots, thus locking the lower andupper covers at. right angles to the back. The numeral 26 indicates a, supporting plate, with posts 27 and 28, designed to telescope within their 24, the function of sheets on the parts 23 and'24, but toserve as a base, or supporting means for suchof plates however, being of equal length, so that when they are threaded through their respective perforations, they rest against respective posts 23 andthe plate and its posts beingnot only to assist in retaining the filed the surface of their companion plate, the 7 papers being held between the plates. The Y 7 function of the plates and posts, and the results obtained are the same in this modi fied form as in mypreferred'form.

Having thus described m invention what forcing theslots overthe rods and'causing I claim and desire to secure by Letters Patent of the United States is:

t; 1. A loose leaf file comprising a back and upper and lower covers loosely secured together, each of said covers also having a hinge near its inner end; a plate, havlng orificed flanges on each of its ends, mounted on theupper surface of the lower cover and inside of the hinged portion thereof, said plate also having upwardly projecting hollow posts secured thereto; a wire spring overlying said plate, its ends projecting through the orifices in the flanges, said spring lying on the inner side ofthe upright posts; right angular plates joining rigidly at right angles the back and the inner hinged P01111011 of the upper cover, each of'said plates being provided with recesses to receive the ends of the wire spring and thereby secure the'back in right angularposition with the inner hinged portion of the lower cover-5a carrier plate provided with posts designed to telescope within the upright hollow posts, substantially as shown and described. 1

2. A loose leaf file comprising a back and upper and lower covers loosely secured thereto, said covers also having hinges near their inner ends; a plate, having orificed flanges on each of its ends, mounted on the upper surface of the lower coverand inside of the: hinged portion thereof, said plate also having upwardly projecting hollow posts secured thereto; a wire spring overlying said plate,itsends proj ectinglthrough the orifices in the flanges, said spring lying on the inner side of the upright posts; right angular foregoing specificatlon.

plates joining rigidly at right angles the back and the inner hinged portion of the upper. cover, each of said plates being provided with recesses to receive the ends of the near its inner end, aplate having orificed flanges on each of its ends, mounted on the upper surface of the lower cover and inside of the hinged portion thereof, said plate also having upwardly projecting posts secured thereto to engage perforations in the sheets to be bound,a wirespring overlying saidplate, its ends projectingthrough the orifices in the flanges, said sprlng lying on the inner side of the upright posts, right angular plates joining rigidly at right angles the back and the inner hinged portion of the upper cover, each of said plates being 7 provlded with recesses to receive the ends of a the wire spring and thereby secure the back in right angular position with the inner hinged portion of the lower cover, a carrier plate provided with posts designed to engage their respective perforations in the sheets to be bound, substantially as shown and described.
